Weld Neck Flanges

We are engaged in providing Weld Neck Flanges that is fabricated to transfer stress to the pipes to minimize the high stress concentrations occurred on the base of the flange. Our Weld Neck Flanges are highly efficacious that render consistent performance for longer period of time. Salient Features :

• Tapered hub
• Gentle transition from flange thickness to pipe wall thickness
• Deformation-resistant
